During a news conference Tuesday, it was confirmed that Williams will play the Jan. 15-28 competition to defend her title at the Australian Open.

Williams has talked about her return to competitive tennis in January 2018.

During the TED 2017 Conference in Vancouver, Williams told Gayle King, “I definitely plan on coming back. I’m not done yet. If [my sister Venus Williams is] still playing, I know I can play. This is just a new part of my life. My baby’s going to be in the stands and hopefully cheering for me.”

The tennis star and her fiancé, Reddit co-founder Alexis Ohanian, 34, welcomed their first child on Sept. 1.

Alexis Jr. arrived at St. Mary’s Medical Center in West Palm Beach, Florida, weighing in at 6 lbs., 13 oz.
